cwt — Provider (Claude or Codex) Worktree Manager

A terminal UI for running parallel provider (Claude or Codex) sessions in isolated git worktrees. Built in Rust, uses tmux for all interactive session management, and requires tmux to be installed.

The worktree is the first-class primitive — sessions attach to worktrees, not the other way around.

Worktree (unit of work)
  |-- Branch (auto-created or user-specified)
  |-- Session (provider instance, 0 or 1 active)
  |-- Lifecycle: ephemeral | permanent
  |-- State: idle | running | waiting | done | shipping

Why cwt?

When using a provider (Claude or Codex) on a real codebase, you often want to run multiple tasks in parallel — fix a bug, add a feature, write tests — without them stepping on each other. Git worktrees give you cheap, isolated copies of your repo. cwt manages the lifecycle of those worktrees and the provider sessions inside them, all from a single TUI.

Spin up a worktree in seconds — auto-named, auto-branched, ready to go
Never lose work — every deletion saves a .patch snapshot first
Stay organized — ephemeral worktrees auto-clean; permanent ones stick around
See everything at once — two-panel TUI with live session status, diff stats, and transcript previews
Scale up — dispatch tasks in bulk, import GitHub issues, broadcast prompts across sessions

Requirements

git (with worktree support)
tmux (mandatory; interactive mode and session management depend on it)
A provider CLI (claude or codex)

Optional:

gh (GitHub CLI) — for PR creation and CI status
podman or docker — for per-worktree containers
ssh — for remote worktrees

Installation

Cargo (from crates.io)

cargo install cwt

cargo install does not install tmux for you. Install tmux separately and make sure it is on your PATH before running cwt.

Nix (recommended)

cwt provides a Nix flake with builds for Linux and macOS (x86_64 and aarch64). The Nix package includes tmux and git as runtime dependencies and wraps the binary so they are always on PATH.

# Run without installing
nix run github:0dragosh/cwt

# Install to your profile
nix profile install github:0dragosh/cwt

Add to a flake-based NixOS or home-manager configuration:

# flake.nix
{
  inputs.cwt.url = "github:0dragosh/cwt";

  # Option 1: use the overlay
  nixpkgs.overlays = [ cwt.overlays.default ];
  # then add pkgs.cwt to your packages

  # Option 2: reference the package directly
  environment.systemPackages = [ cwt.packages.${system}.default ];

  # Option 3: home-manager module (generates ~/.config/cwt/config.toml)
  imports = [ cwt.homeManagerModules.default ];
  programs.cwt = {
    enable = true;
    settings.session.default_permission = "elevated";
  };
}

See docs/nix.md for full home-manager module documentation.

From source

git clone https://github.com/0dragosh/cwt.git
cd cwt
cargo build --release
# Binary at target/release/cwt — add it to your PATH

Make sure git is on your PATH, and make sure tmux is installed and on your PATH. cwt cannot run its interactive workflows without tmux.

Quick Start

tmux is a hard dependency. If you launch cwt from a regular interactive shell, it will bootstrap into tmux automatically when possible, but tmux still must be installed locally.

# 1. Navigate to any git repo
cd ~/my-project

# 2. Launch the TUI (cwt will bootstrap into tmux if needed)
cwt

# 3. Press 'n' to create a worktree (Enter for auto-generated name)
# 4. Press 's' to launch a provider session in it
# 5. Press 'Tab' to switch between the worktree list and inspector panels

Or use CLI commands directly:

cwt create my-feature --base main     # Create a worktree
cwt list                               # List all worktrees
cwt delete my-feature                  # Delete (saves a snapshot first)

# Dispatch parallel tasks — one worktree + session per task
cwt dispatch "implement auth" "add tests" "update docs"

# Import GitHub issues as worktrees
cwt import --github --limit 5

# Multi-repo mode
cwt add-repo ~/code/project-a
cwt add-repo ~/code/project-b
cwt forest                             # Launch forest TUI
cwt status                             # CLI summary across repos

Features

Worktree Management

Create with auto-generated slug names or explicit names, from any base branch
Two-tier lifecycle: ephemeral (auto-GC'd) and permanent (never auto-deleted)
Promote ephemeral worktrees to permanent with a single keypress
Snapshots: full diff saved as .patch before every deletion
Restore previously deleted worktrees from their snapshots
Garbage collection: prune old ephemeral worktrees, skipping those with running sessions, uncommitted changes, or unpushed commits
Setup scripts: automatically run a script (e.g., npm install) after worktree creation

TUI Interface

Two-panel layout: worktree list (grouped by lifecycle) + inspector (details, diff stat, session info)
Fuzzy filter: / to search/filter worktrees by name
Help overlay: ? for a full keybinding reference
Mouse support: click to select, scroll to navigate
Status bar: notification badges for waiting/done sessions

tmux Session Management

Session Providers

cwt supports two provider options: claude and codex
You can set the default in config with session.provider = "claude" or "codex"
You can change the active provider at runtime by pressing o in the TUI
Press O to persist the currently selected provider as the default
Launch the provider (Claude or Codex) in a tmux pane attached to any worktree
Resume previous sessions using the active provider's resume flow (--resume for Claude)
Focus an existing session pane with a single keypress
Open shell in any worktree directory via a tmux pane
Sessions survive TUI exit — closing cwt does not kill running sessions

Handoff

Bidirectional patch transfer between your main working directory and any worktree
Direction picker: worktree-to-local or local-to-worktree
Diff preview before applying
Gitignore gap warnings for untracked files that won't transfer

Hooks (Real-Time Provider Integration)

Unix domain socket listener for sub-second event delivery
Worktrees created by the provider (Claude or Codex) outside cwt appear in the list within one second
cwt hooks install patches .claude/settings.json and writes hook scripts to .cwt/hooks/

Forest Mode (Multi-Repo)

Register multiple repos with cwt add-repo <path>
Three-panel TUI: repos | worktrees | inspector
Aggregate session counts across all repos
cwt status for a one-line CLI summary

Agent Orchestration

Dispatch multiple tasks in parallel: cwt dispatch "task 1" "task 2" ...
Import issues from GitHub or Linear — creates worktrees and sessions per issue
Broadcast a prompt to all running sessions simultaneously

Ship Pipeline

Create PR from a worktree with auto-generated body from session transcript
CI status tracking: pass/fail/pending via gh run list
Ship it: one-keypress macro to push, create PR, and mark as shipping

Per-Worktree Containers

Podman or Docker support (prefers Podman for rootless compatibility)
Auto-detect Containerfile, Dockerfile, or .devcontainer/devcontainer.json
Port management: auto-assign non-conflicting ports per worktree

Permission Levels

cwt supports three permission tiers for provider sessions (Claude/Codex), giving you fine-grained control over how much autonomy the provider gets:

Level	Badge	Behavior
Normal	`N` (gray)	Plain provider command — asks for permission on each tool use (default)
Elevated	`E` (yellow)	Injects sandbox settings into `.claude/settings.local.json` — the provider runs autonomously within a sandbox
Elevated Unsandboxed	`U!` (red)	Appends `--dangerously-skip-permissions` — full autonomy, no sandbox

Press m to cycle through modes at runtime
Press M to save the current mode as the default in your config
The active level is shown as a badge in the top bar
Each worktree gets its own .claude/settings.local.json, so there are no concurrency conflicts between sessions

Provider-specific mode behavior:

Claude: Elevated injects sandbox settings; Unsandboxed uses --dangerously-skip-permissions.
Codex: Unsandboxed uses --full-auto; Elevated Unsandboxed uses --dangerously-bypass-approvals-and-sandbox.

The elevated (sandboxed) provider mode writes these settings before launch:

{
  "permissions": { "allow": [], "deny": [] },
  "sandbox": {
    "enabled": true,
    "autoAllowBashIfSandboxed": true,
    "allowUnsandboxedCommands": false
  }
}

Troubleshooting

cwt says "tmux is required" tmux is a mandatory runtime dependency. Install it first, then run cwt again. If you launch cwt from a normal interactive shell, it will bootstrap into tmux automatically when possible.

Worktrees don't appear after a provider creates them Run cwt hooks install to set up the real-time hook integration. Without hooks, cwt discovers worktrees on periodic refresh (every few seconds).

gh commands fail (PR creation, CI status) Make sure the GitHub CLI is installed and authenticated (gh auth login).

Sessions show "idle" even though the provider is running cwt detects session status by parsing ~/.claude/projects/ transcripts. If the path hash doesn't match, status won't update. Restarting cwt re-scans the project directory.

GC skipped a worktree I expected it to prune GC never prunes worktrees with running sessions, uncommitted changes, or unpushed commits. Check cwt list for details.
